Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] like Figure 1-4 As shown, a low-temperature curing polyester resin powder production equipment includes a reactor 8, a three-phase asynchronous motor 9 is fixedly installed on the top of the reactor 8, the output end of the three-phase asynchronous motor 9 is connected to a rotating shaft 7 rotatably arranged in the reactor 8, a blade 4 is welded on the rotating shaft 7, the blade 4 includes a horizontal part and an inclined part, and a stirring component is arranged on the inclined part facing the rotating shaft 7;

[0023] The stirring assembly includes a base frame 2 and a rotating seat 1 rotatably disposed on the base frame 2. The rotating seat 1 includes a rotating portion 11, a cutting blade portion 12 and a mounting portion 13 from one side of the base frame 2 to the other side. The cutting blade portion 12 is located between the rotating portion 11 and the mounting portion 13, wherein:

[0024] A V-shaped bracket 31 is fixedly mounted on the mounting portion 13 , and rectangular blocks 3 are fixedly mounted on both ends of the V-shaped bracket 31 .

[0025] Specifically, the stirring assembly is arranged on the inclined portion of the impeller 4. When stirring is performed, the rotating shaft 7 drives the impeller 4 to stir, and the rotating seat 1 rotates so that the breaking blade portion 12 breaks the vortex flow stirred by the impeller 4, and then the V-shaped bracket 31 and the rectangular block 3 realize inclined stirring, thereby optimizing the stirring effect.

[0026] As an embodiment further provided by the present invention, the breaking blade portion 12 can be divided into a plurality of breaking blade plates 121 distributed in a linear array, and the length of the breaking blade plates 121 decreases from the middle to both sides.

[0027] Furthermore, the plurality of breaking blade plates 121 are spaced 10 cm apart.

[0028] Secondly, both ends of the breaking blade plate 121 are in the shape of 60-degree sharp angles. Both ends of the central breaking blade plate 121 are symmetrically provided with raised portions 122 . The raised portions 122 are in the shape of convex arcs and are tangent to the sharp angle surfaces of the ends of the breaking blade plate 121 .

[0029] Specifically, when the rotating part 11 rotates, the vortex flow stirred by the blade 4 will be split by the breaking blade 121 and then guided downward through the protrusion 122, thereby applying a mixing execution.

[0030] As another embodiment further provided by the present invention, a telescopic cylinder 62 is fixedly disposed in the base frame 2, and a push member 61 at the output end of the telescopic cylinder 62 is slidably disposed on the side wall of the rotating part 11. A roller is disposed on the contact surface of the push member 61.

When the telescopic cylinder 62 can drive the rotating part 11 located on the base frame 2 to move along the telescopic direction of the telescopic cylinder 62, the synchronous equidistant springs will also deform with the compression to ensure that the meshing relationship will not be destroyed.

[0034] It should be noted that the elastic coefficient of the equidistant spring in the above embodiment should be greater than the force caused by the rotation when the drive motor 51 outputs the torque force, and the specific value is not disclosed in detail.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
